Building a Corporate CSIRT: Roles, Responsibilities & Operational Tooling
Structuring an internal Computer Security Incident Response Team (CSIRT) capable of triage, analysis, and coordinated remediation.
Defining the CSIRT Mandate
A Computer Security Incident Response Team (CSIRT) is the formalized internal unit responsible for receiving, analyzing, and responding to cyber incidents across the organization.
Key Functional Roles
Incident Commander: Leads response strategy, coordinates resources, and briefs leadership.
Technical Triage & Forensics: Analyzes malware, memory dumps, and network traffic.
Communications & Legal Liaison: Manages law enforcement, regulatory reporting, and internal/external PR.
Infrastructure Remediation: Rebuilds clean systems, deploys patches, and validates restoration.
Equipping the Team with an Out-of-Band Incident Kit
The CSIRT must maintain pre-configured offline laptops, dedicated cellular hot spots, and encrypted out-of-band communication accounts (Signal/ProtonMail) that function independently of corporate infrastructure.
